Associate Professor Ilka Wallis

Ilka Wallis is a quantitative hydrogeologist with an extensive record of applied research in contaminant hydrology and hydrochemistry. Ilka’s major research interest is the development of reactive (bio)geochemical transport models and their application to elucidate the fate of organic and inorganic pollutants at the laboratory-scale and in contaminated aquifers. Areas of specialization include water quality changes during managed aquifer recharge, and the quantifying of feedback mechanisms between chemical reactions and physical flow in aquifer systems.

Ilka obtained her MSc at Christian-Albrechts-University Kiel, Germany and her PhD at Flinders University, and has worked at the Geological Surveys of South Africa, Great Britain and Germany and at Aquaterra Simulations Pty, Australia.
